Operation CHARM: Car repair manuals for everyone.

General Information

CAUTION: Whenever a transmission has been disassembled to install new parts, the transmission fluid cooler must be replaced and the transmission fluid cooler tubes must be cleaned and backflushed.

Note: Cleaning and backflushing the transmission fluid cooling system, along with normal cleaning and inspection procedures as outlined in this section during disassembly and reassembly, will keep contamination from reentering the transmission and causing a repeat repair.

When internal wear or damage has occurred in the transmission, metal particles, clutch plate material, or band material may have been carried into the torque converter and transmission fluid cooler. These contaminants are a major cause of recurring transmission troubles and must be removed from the system before the transmission is put back in use.
